Areas of application for the thermometer optris P20 1M / 2M

The portable thermometers gun optris P20 1M and 2M allow reliable measurement of metallic surfaces of up to 1,800°C (1M), ensuring even more precision due to their selectable emmisivity. Those features make the thermometer indispensable in the metal industry, especially for sporadic measurements. Thus, the handheld laser thermometer is often employed for heated re-forming processes, including cutting, bending, and milling of e.g. steel slabs, ensuring maintenance of required temperature ranges.
